BB^xPROGRESSION/4 Data Server«

Improved Network Performance

You want it when? Does your network seem to be laughing while you wait for it to retrieve your remote data? The BB^XPROGRESSION/4 Data Server can help your networks respond more like local access!

Networks and client/server technology have become an integral part of the business computing environment. As the use of networks grows, so do the problems of efficiently sharing common data. Anyone who has tried to retrieve data across a busy network knows that this can be slow and frustrating

Until Now!

The BB^XPROGRESSION/4 Data Server improves performance over network transparent file systems like Network File System (NFS), Remote File System (RFS), or Novell NetWare. The Data Server improves the speed of remote data access on either wide area or local area networks by reducing the number of network transactions required.

Remote File, Local Control

When BB^X accesses a remote file through a network transparent file system, it issues the same commands that it would for a local file and lets the network transparent file system handle the differences. When the BB^XPROGRESSION/4 Data Server is active on the system where BB^X accessible files reside, this flurry of network transactions is reduced to two:

The client sends a single message to the Data Server requesting the record
The Data Server returns the record to the client

All other transactions are performed locally, and quickly, by the Data Server. This improves both the performance of the network and the performance of BB^X when remote files are accessed.

Security

The BB^XPROGRESSION/4 Data Server is designed to function within the security constraints of the host operating system. It will not introduce security risks when used correctly. The Data Server enforces Novell access rights. Under the UNIX operating system, much of the security is provided by TCP/IP.

System Requirements

Use of the BB^XPROGRESSION/4 Data Server in the UNIX operating system environment requires a network protocol common to both the server and the client systems (TCP/IP,XNS, OSI, etc.) which offers a Berkeley Socket Interface Library as a communication interface. Each system that will act as a server by providing BB^X data to others on the network must have a Data Server installed. And, each system that will act as a client by requesting BB^X data from a server must have its own client-ready copy of BB^XPROGRESSION/4 installed.

In the Novell NetWare environment, a Data Server must be installed on each file server as a Network Loadable Module (NLM). Also, a client-ready BB^XPROGRESSION/4 that is licensed for an adequate number of users must be available somewhere on the network.

The Bottom Line: Productivity

The BB^XPROGRESSION/4 Data Server improves the performance of BB^X applications in a network environment by decreasing the network overhead associated with accessing remote files. Improved performance means:

Vital BB^X data gets processed in less time, while maintaining data security and integrity
Overall network productivity is enhanced

Add the BB^XPROGRESSION/4 Data Server to your BB^X developer's toolkit and remain one step ahead all over the world.
